mTOR Inhibition and Cardiovascular Diseases: Dyslipidemia and Atherosclerosis

Inhibitors of the mechanistic target of rapamycin (mTOR) have unique antiatherosclerotic effects, such as depletion of plaque macrophages, induction of autophagy, and activation of cholesterol efflux. However, a common side effect of their use is dyslipidemia, a well-known risk factor for atherosclerosis. Indeed, mTOR inhibitors prevent lipid storage, increase low-density lipoprotein cholesterol levels, and activate lipolysis. Although the net effect of mTOR inhibition seems favorable, the use of cholesterol lowering drugs to manage dyslipidemia remains the most recommended strategy.
